Does music have any intellectual content?

As opposed, I suppose you mean, to affective or emotional content? Yes, both in the lyrics or librettos of various musical compositions and in the web work of meanings that have come to be attached to various sounds. Like most, if not all, artforms, music exists in an historical context, and within any context music relates to other music. So rhythms, harmonies, instrumentation, chord progressions, intonation, etc. evoke symbols, social ideas, abstract ideas concerning music theory, social criticism, human relationships, the divine, etc. Musical compositions themselves are associated with cultural movements (modernism, tradition, militancy, rebellion), fashion, politics, even entire civilizations (the Europe, Africa, India). When we listen to a song, we listen to a history and to a society.
